2. The sidelink communication method according to claim 1, wherein the plurality of zone types are classified into a high-zone and a low-zone, the high-zone and the low-zone have different sizes, the high-zone is selected among the plurality of zone types when the speed of the UE is equal to or greater than a speed threshold, and the low-zone is selected among the plurality of zone types when the speed of the UE is less than the speed threshold.
This invention relates to sidelink communication in wireless networks, specifically addressing the challenge of optimizing resource allocation for user equipment (UE) operating at different speeds. The method dynamically selects communication zones based on UE speed to improve efficiency and reliability. The zones are classified into two types: high-zones and low-zones, which differ in size. High-zones are larger and are used when the UE's speed is at or above a predefined threshold, ensuring broader coverage and better connectivity for fast-moving devices. Low-zones are smaller and are used when the UE's speed is below the threshold, allowing for more precise resource allocation and reduced interference in slower-moving scenarios. The selection of zone type is determined by comparing the UE's current speed to the threshold, enabling adaptive communication strategies that balance coverage, resource usage, and interference management. This approach enhances sidelink communication performance by tailoring zone selection to the UE's mobility state, ensuring optimal operation across varying conditions.
3. The sidelink communication method according to claim 2, wherein the zone configuration information includes the speed threshold.
This invention relates to sidelink communication in wireless networks, specifically addressing challenges in managing communication between devices in high-mobility scenarios. The method involves configuring communication zones based on device speed to optimize resource allocation and reduce interference. A key aspect is the inclusion of a speed threshold in zone configuration information, which determines whether a device operates in a high-mobility or low-mobility zone. Devices exceeding the speed threshold are assigned to a high-mobility zone, where communication parameters are adjusted to account for faster movement, such as shorter transmission intervals or larger resource blocks. Conversely, slower devices are placed in a low-mobility zone with different parameters to improve efficiency. The speed threshold ensures dynamic adaptation to varying mobility conditions, enhancing reliability and throughput in sidelink communications. This approach is particularly useful in vehicular networks or other environments where device mobility significantly impacts communication performance. The method may also involve periodic updates to the speed threshold based on network conditions or device behavior to maintain optimal performance.
4. The sidelink communication method according to claim 2, wherein the resource pool configuration information includes configuration information of resource pools for the high-zone and configuration information of resource pools for the low-zone.
This invention relates to sidelink communication in wireless networks, specifically addressing the challenge of efficiently managing resource allocation for devices operating in different coverage zones. In wireless communication systems, devices may be located in areas with varying signal quality, such as high-coverage zones (e.g., near a base station) and low-coverage zones (e.g., at the network edge). The invention provides a method for configuring and utilizing separate resource pools for these zones to optimize communication performance. The method involves transmitting resource pool configuration information to user equipment (UE), where the configuration includes distinct settings for high-zone and low-zone resource pools. These pools are tailored to the specific conditions of each zone, such as signal strength, interference levels, and device density. By separating the resource pools, the system can allocate resources more effectively, reducing interference and improving reliability for devices in both zones. The configuration information may include parameters like frequency bands, time slots, or power levels assigned to each pool, ensuring that devices in different zones can communicate without mutual disruption. This approach enhances sidelink communication efficiency by dynamically adapting resource allocation based on the coverage conditions, leading to better overall network performance and user experience. The method is particularly useful in scenarios where devices are distributed across areas with varying signal quality, such as in vehicle-to-everything (V2X) or machine-type communications (MTC).
5. The sidelink communication method according to claim 1, wherein the plurality of zone types are classified into a high-zone, a medium-zone, and a low-zone, the high-zone, the medium-zone, and the low-zone have different sizes, the high-zone is selected among the plurality of zone types when the speed of the UE is equal to or greater than a first speed threshold, the medium- zone is selected among the plurality of zone types when the speed of the UE is less than the first speed threshold and equal to or greater than a second speed threshold, the low-zone is selected among the plurality of zone types when the speed of the UE is less than the second speed threshold, and the first speed threshold is greater than the second speed threshold.
6. The sidelink communication method according to claim 1, wherein the message is a system information block (SIB).
This invention relates to sidelink communication in wireless networks, specifically improving the transmission of system information blocks (SIBs) between devices. In wireless communication systems, sidelink enables direct device-to-device communication without relying on a base station, which is crucial for applications like vehicle-to-everything (V2X) and machine-type communications. A key challenge is efficiently distributing system information, such as SIBs, which contain essential network configuration details, to devices in a sidelink environment. The invention addresses this by defining a method where a device transmits a SIB over a sidelink channel. The SIB may include parameters like cell selection criteria, frequency bands, or other network-specific configurations. The transmitting device may receive the SIB from a base station or another device and then relay it to neighboring devices via sidelink. This ensures that devices in the network can access critical system information even when they are not directly connected to a base station. The method may also involve error handling, retransmission mechanisms, or synchronization to ensure reliable delivery. By enabling SIB transmission over sidelink, the invention enhances network flexibility and reduces reliance on infrastructure, particularly in scenarios with limited base station coverage or high device density.
9. The operation method according to claim 8, wherein the plurality of zone types are classified into a high-zone and a low-zone, the high-zone and the low-zone have different sizes, the high-zone is selected among the plurality of zone types when the speed of the UE is equal to or greater than a speed threshold, and the low-zone is selected among the plurality of zone types when the speed of the UE is less than the speed threshold.
This invention relates to wireless communication systems, specifically to methods for selecting zone types in a network to optimize resource allocation based on user equipment (UE) speed. The problem addressed is inefficient resource utilization when UE speed is not considered in zone selection, leading to suboptimal performance in terms of coverage, capacity, and energy efficiency. The method involves classifying zones into at least two types: a high-zone and a low-zone, which differ in size. The high-zone is selected when the UE's speed is equal to or greater than a predefined speed threshold, while the low-zone is selected when the UE's speed is below the threshold. This dynamic selection ensures that faster-moving UEs are assigned larger zones to maintain stable connections, while slower UEs are assigned smaller zones to improve spectral efficiency and reduce interference. The method may also involve determining the UE's speed using location information or other mobility metrics, and adjusting zone selection accordingly. By adapting zone types based on UE speed, the system optimizes network performance for varying mobility conditions.
10. The operation method according to claim 9, wherein the zone configuration information includes the speed threshold.
A system and method for managing vehicle operations within designated zones, particularly in environments like warehouses or industrial facilities where vehicles such as forklifts or automated guided vehicles (AGVs) operate. The technology addresses the challenge of ensuring safe and efficient movement of vehicles by dynamically adjusting operational parameters based on predefined zone configurations. These zones may have different operational requirements, such as speed limits, to prevent collisions or optimize workflow. The method involves monitoring the vehicle's position and applying specific operational rules when the vehicle enters or exits a zone. The zone configuration information includes a speed threshold, which defines the maximum allowable speed for vehicles within that zone. When a vehicle enters a zone, its speed is automatically adjusted to comply with the threshold, ensuring adherence to safety and efficiency standards. The system may also include additional zone-specific parameters, such as acceleration limits or directional constraints, to further refine vehicle behavior. This approach enhances safety by preventing excessive speeds in high-risk areas while maintaining productivity in less restrictive zones. The method is particularly useful in environments where multiple vehicles operate in close proximity, reducing the risk of accidents and improving overall operational efficiency.
